i've got toto.py :
import titi
def niwhom():
pass
and titi.py :
def nipang():
pass
how can i know in titi.py that's it's toto.py that is calling titi.py
and the path of toto ?
You'd have to inspect the call stack. Not for the faint at heart...
And
why :
bidule.py :
class bidetmusique:
pass
<OT>
The naming convention is to capitalize class names, ie "Bidetmusique" or
"BidetMusique"
</OT>
<OT mode="even-more">
Heureusement qu'il n'y a pas grand monde ici pour comprendre le
français, parce que comme nommage, ça bat des records, là !-)
</OT>
truc.py :
X = __import__("bidule")
why exec("X.bidetmusique()") return none
exec doesn't "return" anything - it executes code in a given context,
eventually modifying the context. Now given your above code, a new
bidetmusique instance is indeed created, but since it's not bound to
anything, it's immediatly discarded.
and X.bidetmusique() return an object ?
cf above
How could i do to make this string "X.bidetmusique()" return an object ?
exec is 99 time out of 10 (nope, not a typo) the wrong solution. You
already found how to dynamically import a module by name (I mean, name
given as as string), all you need know is to find out how to dynamically
retrieve a module attribute given it's name as string. And the answer is
"getattr":
# truc.py :
X = __import__("bidule")
cls = getattr(X, "bidetmusique")
obj = cls()
print obj
